Holy Cow!
How big a pump would it take to drive on of those bruiser cylinders?!
Want kind of tonage would a press with one of those puppies output?! I just got in on this thread. I love your ideas, guys, for the portable press. Dana |

Nice compact press Cal. Do you ever have a hard time seeing around the dies or keeping an eye on how the billet is forming out the back side of the press.
On those specs above, would you want a tad more speed on the ram to keep the dies from drawing too much heat out of the work. Just wondering. Thanks for your knowledge, Craig |

Yes with only 5 gallons a minute this would be a little slow so you could either put a larger pump on which would require a larger motor or the other option is to design the circuit with a regeneration function then the press speeds would be as follows with the same 5 GPM pump. The cylinder would then approach the billet at almost 1 inch per second until the force reached 29438 pounds then it could switch back to it slow speed and maximum force. That is how my press works because I do not have access to 220V to run a 5 HP motor. REGENERATION FORCE 29,438 LBS REGENERATION VELOCITY 0.98 IN/SEC EXTEND TIME 14.27 SEC.

Thanks for the explanation Cal. Sounded interesting so I looked around and stumble on a posting you did over on britblades. Good stuff.
Take care, Craig |

I'm sorry or bumping an old thread, but I found this image on google search (I want to build my own forging press) and I was wondering if there are any follow-up threads on this particular press. Thanks. |

Hello all, I'm new to this forum. I found it looking for information on hydraulic forging presses. I'm sorry for waking the dead on this thread. But it looks interesting. Are there any threads or additional information like websites, on it?

I doubt you'll find any websites that are dedicated to forging presses. The reason? The huge safety/liability issues that come along with a forging press. Most of us piece the information together from various sources..... and a LOT of help from others who have built and/or use these machines.
